OK, about that Tawfik paper on arsenate resistance

Nice work. But I think it should be of interest only to people who care about the biochemistry of arsenic resistance, a set that doesn't include me.

GFAJ-s level of arsenate resistance is not all that exceptional. What was important about the Wolfe-Simon et al. paper was the claim that GFAJ-1 actively incorporates arsenic in place of phosphorus. We already know that this claim was an error (the sum of many errors) by the authors.

I'm returning my attention to the much more interesting question of whether bacteria have any functional parallel to the meiotic sex of eukaryotes.
